x86/boot/e820: Prefix the E820_* type names with "E820_TYPE_"
So there's a number of constants that start with "E820" but which
are not types - these create a confusing mixture when seen together
with 'enum e820_type' values:
E820MAP
E820NR
E820_X_MAX
E820MAX
To better differentiate the 'enum e820_type' values prefix them
with E820_TYPE_.
No change in functionality.
